My 18 month old dog has suddenly gone from being one that loved nothing more than to sit at my feet during the day (if not out on walks) to one who wants to permanently reside in the garden. Sometimes he comes up to the door, I open it to let him in, he looks a bit unsure then decides to go back to his spot on the decking, against the door - where he can see me. Why ?? Not a big problem, but wonder what's going on in his furball brain... is it 'cos i've got the heating on more ? or is he just growing up? all thoughts welcome !
